500 Address (BUS ADDRESS)
Settings:
1 - 126
1
Function:
This parameter allows specification of the address of
each FCM 300. This feature is used in connection
with PLC/PC connection.
Description of choice:
The individual FCM 300 can be given an address
between 1 and 126. The address 0 is used if a
master (PLC or PC) wishes to send a telegram that
is to be received by all FCM 300 connected to the
serial communication port at the same time. In this
case, the FCM 300 will not acknowledge receipt. If
the number of units connected (FC M 300 + master)
exceeds 31, a repeater is required.
501 Baudrate (BAUDRATE)
Settings:
300 Baud (300 BAUD)
600 Baud (600 BAUD)
1200 Baud (1200 BAUD)
2400 Baud (2400 BAUD)
4800 Baud (4800 BAUD)
9600 Baud (9600 BAUD)
Function:
This parameter is for programming the speed at
which data is to be transmitted via the serial
connection. Baud rate is defined as the number of
bits transferred per second.
Description of choice:
The transmission speed of the FCM 300 is to be set
at a value that corresponds to the transmission
speed of the PLC/PC.

Function:
Parameters 502-508 allow a choice between
controlling the FCM 300 via the terminals (digital
input) and/or via the bus.
If (Logic and) or (Bus) is selected, the command in
question can only be activated if transmitted via the
serial communication port. In the case of Logic and,
the command must additionally be activated via one
of the digital inputs.

[3]
question is only to be activated via a digital input.

[5]
Bus [1] is selected if the control command in
question is only to be activated via a bit in the
control word (serial communication).
Logic and [2] is selected if the control command in
question is only to be activated when a signal is
transmitted (active signal = 1) via both a control
word and a digital input.
